To all whom it may concern.-

Be it known that we, ALBERT LLOYD and WILLIAM FREDERICK GLYDoN, subjectsof the Queen of Great Britain, residing at Birmingham, in the county ofVvarwick, England, manufacturers, have invented certain new and usefulImprovements in the Manufacture or Production of Scissors and such likeCutting- 1 Instruments, (for which we have applied for Letters Patent inGreat Britain, No. 1,121, dated 10th day of January, 1884,) of whichthefollowing is a specification.

Our invention has for its object the production or manufacture ofscissors and such like cutting-instruments from metallic wire or rods ofany suitable metal by the process or combination of steps,hereinafterdescribed,whereby wrought scissors are produced in a simpler and moreefficient manner than heretofore.

We will now describe the production of scissors from wire. We take wireof any suitable size and of sufficient length to form out of one pieceboth the blade and stem part, which latter is afterward bent intofinger-bows-that is, a length of wire of uniform gage is bent near itsmiddle, which afterward forms the shank or stem of one arm of a pair ofscissors. The metal of the one side of the bend is next sub jected tothe action of flattening or pressure dies in such a manner that the wireshall be at one part flattened out, while the other part is left plainor unoperated upon. The flattenedout part constitutes the blade orcutting part of the instrument, while the plain or other part so leftforms the shank and metal to form-the bow of one half of a pair ofscissors. Two such arms or levers, when crossing each other and jointedtogether near their middles,constitute a pair. of scissors.

We will now proceed to describe, with reference to the accompanyingdrawings, the manner in which our invention is to be performed.

Figure 1 represents a pair of scissors made according to the first partof our invention. Fig. 2 represents a piece of round wire or rod fromwhich one of the arms or levers of the scissors, Fig. 1, is made. Figs.3, 4, 5, and 6 wire, Fig. 2, passes in the production of onehalf of apair of scissors, as represented in either Fig. 6 or 7.

In making a pair of scissors according to our invention, Fig. 1, we takea piece of wire ora rod of steel or of any suitable metal. (Shown atFig. 2.) The said wire or rod is next bent at a, as shown in Fig. 3,which forms the shank of the scissor arm. The part a, extending from thebend a to the end thereof, is next subjected to the action of a pair ofdies worked in a press or stamp in such a manner as to flatten out andshape the metal at that part so operated upon. The flattening andshaping described give the requisite form to the blade or cutting partof the scissors, as shown at b, Fig. 4. Fig. 4* represents the underside of the said Fig. 4, while Fig. 4 is a cross-section on the dottedlines, the blade I) being slightly twisted or concaved for giving theproper cutting to the edge. pierced with the rivet-hole c. We next bendup the end of the wire a into the finger bow or loop 11 Fig. 7 is anunder side of Fig. 6. By now taking the two arms or levers, Figs. 6 and7, and crossing and joining them together by a rivet through therivet-hole c, the scissors, Fig. 1, is thereby produced.

\Vhen itis required that the finger bow or loop and the shank part ofthe arms of the scissors should be made lighter in metal than the bladepart-that is to say, where a preponderance'of metal is required to bedisposed in the blade part, while the shank or bow part partly-reduceddiameter is marked d, which may be elliptical, circular, orany othersuitable form in cross-section. The thick and reduced or shaped parts ofthe wire dd ,'Figs. 9, 10, 11, and 12, are subsequently operated uponfor the bending, flattening, shaping, pierc- The blade b, Fig. 5, isnext is required to be more slender-we proceed aslength only, asrepresented at Fig. 9. "The.

represent the various steps through which the I ing, and the bending upor shaping of the loop or finger-bow, as before described, therebyproducing scissors with light shanks and slim finger-bows, asrepresented at Fig. 13. The blades are afterward properly ground andfinished in any desired way, as shown in Fig. 14.

Having fully described our invention, and the manner in which the sameis to be performed, we wish it to be understood that what we desire toclaim, and secure by Letters Patent, is

1. The process for the manufacture of scissors from metallic wire orrods of uniform gage, consisting in taking a section of wire of uniformgage and of sufficient length and thickness, bending the section at themiddle part to form the shank, then subjecting the metal at one side ofthis bend to the action of flattening or pressing dies to form theblade, and then bending the ends of the section to form the iinger-bows,substantially as set forth and shown. 2. In the manufacture of scissorsfrom Wire or rods of uniform gage, the method consisting in firstdrawing a portion of the rod or Wire section to a diminished thicknessor diameter to form the finger-bows and shank, then bending the metal atthe middle part to form the shank, next subjecting the metal at one sideof such bend to the action of pressure or flattening dies to form theblade, and finally bending the ends to form finger-bows, as shown anddescribed.
